WEARING-PLATE FOR MOWING-MACI-IINES.

Specification of Letters Patent. Patented Aug. 20, 1918.

Application filed December 1, 1915. Serial No. 64,518.

following is a specification, reference being had to the accompanying drawings.

This invention relates to wearing-plates used in connection with the sickle :of' a mowing machine and adapted to receive the backward and downward pressure of the sickle as it is reciprocated in' operation. It is one ofthe objects of my invention to provide a wearing-plate of this type so arranged as to be adapted to present either of two wearing parts for contact with the sickle, whereby the plate is made operative in a plurality of reversed positions. By the use of my expedient I am enabled to provide a reversible plate of this'character by the use of a very small amount of additional material at a substantially negligible increase in cost, serving to double the life of the wearing-plate. This expedienthas the additional advantage that when one of the wearing surfaces becomes worn another operative wearlng part is immedlately available without any possible question as to where a repair or exchange plate has been stored for safe keeping pending its use. It is another. object of my invention to improve mechanisms comprising finger-bars, sickles and wearing-plates in sundry details hereinafter pointed out. The preferred means by which I have accomplished the objects of my invention are illustrated in the accompanying drawings and are hereinafter specifically That which I believe to be new this application is described. and desire to cover by set forth in the claims. 7

In the drawings, Figure 1 is a fragmentary top view showing the connection between the finger-bar and the inner shoe by which the finger-bar is carried;

Fig. 2 is a vertical cross-section through the finger-bar, being taken substantially on line 2-2- of Fig. 1; and

Fig. 3 is an enlarged detail, being a perspective view of one of the-wearing plates.

Referring to the several figures of thedrawings, in which corresponding parts are indicated by the same referencecharacters,

10 indicates the inner shoe of a mowing machine adapted to be connected in position by means of perforated lugs or cars 11-12.

A finger-bar 13 is secured atits inner end to the shoe 10 by means of bolts 14,-a wearing-plate 15 and a keeper 16 being secured by said bolts in position above the end of the finger-bar. It will be understood that in a complete machine aplurality of wearingplates and keepers are employed, spaced at intervals 'along the finger-bar 13, as is the ordinary practice. I The sickle employed is of the ordinary type comprising a bar17, blades or sections 18 riveted thereto, and an operating head 19 secured upon the inner end of the bar 17.

tending beyond the rear edge of the sickle bar, providing thus a longitudinally-extendpitman connected by suitable socket means with a ball 21 forming a part of the head 19. As in ordinary practice, guards 22 are The rear edges of the sections are shown exmounted upon the finger-bar 13 at intervals,

the guards 22 being provided with ledgerplates 28 provided with cutting edges adapted to cooperate with the cutting sections. 18 of the sickle, as is well understood in the art. A ledger-plate 23 is also carried by the shoe 10, as shown in Fig. 2, adapted to cooperate with the innermost section 18 of the sickle. The keeper 16 at the inner end of the fingerbar 13 is provided with a perforated arm 24 for controlling the position of the finger-bar as may be desired.

As is best shown in Fig. 2, the wearingplate 15 is provided with a downwardly-ex I I bears at its rear edge against the flange 25,

while the under faces of the bladesor sections 18 bear upon the upper face of the wearing-plate at its forward edge. In the construction shown, the wearing-plate 15 is also provided at its rear edge with an upwardly-extending flange 26. As will be readily understood, when the portions of the Wearing-plate 15 which are in contact with the sickle-bar l7 and the blades 18 of the sickle become worn by reason of the backward and downward pressure thereon in use, the plate 15 is adapted to be removed and easily and quickly replaced with the flange 26 in position to take the backward pressure of the sickle-bar 17. Thus by the use of the construction illustrated, by means of the very small additional amount of material involved in the provision of the flange 26, the life of the wearing-plate 15 as an efl'ective element of the construction is doubled.

So far as I am aware, I am the first in the art to provide a Z-shaped wearing plate either flange of which may be used as desired for receiving the Wear of the sickle,

and the first to provide a wearing plate having flanges at its oppositeedges whether of a2 form or not which can be used with either flange as desired positioned along the forward edge of the finger bar and adapted in such position to receive both the backward and the downward pressure of the sickle, and my claims are to be construed accordingly.

That which I claim as my invention, and desire to secure by Letters Patent, is,

1. A reversible wearing-plate for mowing-machines, said plate having a flange extending substantially at right angles to the plate along each of its front and rear edges so that either flange may extend into the space between adjacent edges of a finger-bar and sickle-bar when the plate is in position upon the machine.

2. A reversible wearing-plate for mowing-machines, said plate having a flange at each of its front and rear edges extending substantially at right angles from the plate and in opposite directions so that either flange may extend into the space between adjacent edges of a finger bar and sickle-bar when the plate is in position upon the machine.
